WHEELWRIGHTS MACHINE.

Specification of Letters Patent No. 32,072, dated April 16, 1.861.

To all whom it 'may concern: p

Be it known that I, C. LUTHER, of Newbury, in the county of Geauga and State of Ohio, have invented certain new and useful Improvements in Machines for Making Carriage-Vheels; and I do hereby declare that the following is a full and complete description ofthe construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figures l, 3, and 4, are side elevations, and Fig. 2, is a top view.

The same letters refer to like parts in the different views.

My improvement, in the first place, relates to an arrangement of devices for boring holes in hubs for the mortises. The hub is placed on a stand and secured in an upright position, having a dial plate attached to the lower end, that serves as an index, by which the hub is divided oif, into equal spaces. The holes arerbored by means of a bit operated by a crank, and pressed in and out by foot power.

My improvement also relates to the manner of tenoning the ends of the spokes, (after they are driven into the mortises formed in the hub), by means of the bit being removed, and the tenoning tool put in its place,

tached a dial plate F, that turns with it. In

the center of this plate is a pin, that passes up into the hub,this together with the standard D, and hand screw E, retains the hub in a vertical position, but allows 1t to be turnedaround. Around the edge. of the dial plate are a number of holes equally distant apart, as shown in Fig. 2.

Gr, Fig. l, is a pin inserted into one of the holes of the dial plate, and put in a hole in the stand, which keeps the hubin place until a hole is bored for one mortise, when the pin is removed, and the hub turned, the dial plate turning with it, until the neXt hole in the plate is over the hole in the stand, when the pin Gr, is again inserted, and so on until the holes for the mortises are all bored.

I-I, is'the bit secured to the end of the shaft I, by the thumb screw J. The shaft I, is supported by the stationary bearings M, and N, and is turned by the crank K. On the shaft I, is a loose collar L, placed between two rings on the shaft, with which are connected the cords S, S', that pass over two pulleys M, and N in the bearings M, and N, down through holes in the stand, and bench and are connectedl with a treadle by means of which the tenoning tool, or bit, is moved either way by foot power, the foot being placed upon the footstep or treadle, to move the bit and tool back and forth; while they are revolved by turning the crank with the hand. In this way the desired workis soon accomplished.

After the holes are all bored in the hub, it is removed from the stand and mortised, when the spokes are set or driven in. P is an adjustable stand screwed to the bench B. The hub is then placed on this stand, the large end downward, the screw P', keeping it in place, as shown in Fig. 3. R, is a hollow auger, or tenoning tool, secured to the end of the shaft I, by the thumb screw J, which passes through an opening in the standard O, at which point there is a box `or bea-ring O, for the outer end of the tool, to hold it firmly and steadily in place. The hub is then adjusted upon the stand P,

in such a way that the ends of the spokes will be in a line with the tenoning tool.

T, is an adjustable standard or screw, on which the ends of the spokes are placed.

T, is an adjust-able thumb screw, passing through the arm O which presses the block P, on the spoke C, thus holding it firmly and securely.

U, is an elastic band,` attached to the side of the block, and passes up over the arm O-, that draws the block up as fast as it is unscrewed.

IVhenall the screws are suitably adjusted, the foot is placed on the treadle, and the crank turned, the spoke will in this way, be speedily tenoned, when the shaft can be slid back, releasing the spoke from the tool. The hub can then be turned around, until another spoke is in the place of the former one, and so on, until the spokes are all uniformly, as well as rapidly tenoned.

Vhen holes are to be made in the fellies, it is necessary to unscrew the nuts c, a, in the standard O, when it can be moved along, in the slots c, c, shown in Fig. 2. The standards Q, and T, are moved by pulling out the slide It', in the stand A, when they are moved a suitable distance, the bit H, is replaced, as shown in Fig. 4, in the shaft I. After the points where the holes are to be made are indicated onV the felly, by placing it around the spokes of the wheel, it is placed on the stand Q, as shown at X, when the block V, is screwed down on the felly, by the hand screw Y, to keep it firmly in place. A hole is then bored in the way before described, when the block V, is unscrewed, and the felly moved along, and another hole bored in the same way and so on.

If the above directions are followed out, a wheel made in this machine cannot be otherwise than perfect in all its parts, be-

that the disk y), upon which the hub rests, forms a nut, which works upward and downward upon the screw P of which the stand is in part composed. In this way, the hub can be adjusted exactly to the point desired-to suit the tenoning tool R. This adjustment is necessary in order to accommodate various lengths of hub.

I do not claim the devices herein named separately considered, for most of them have beenvbefore used in some form; but

What I do claim as my improvement and desire to secure by Letters Patent,lis-

The special arrangement and combination of the several parts, in the manner herein setforth, so that the various kinds of work in making carriage wheels, as boring the hub, tenoning the outer ends of the spokes after they are set, and boring the fellies, may all be performed upon the same machine, placed upon a common work bench and operated by hand, as specified.
